邮箱保活程序-通义千问

毕业也有两三个月了，突然想起来有的学校会在学生毕业之后取消掉edu邮箱，有的学校是如果长时间不使用就收回邮箱。想想自己白嫖来的github教育包，还有其他通过edu邮箱白嫖来的会员，感觉这个邮箱还是很重要的，所以就打算写一个保活程序，每隔一个月发一个邮件证明邮箱还在使用。

写代码是不可能完全自己写的，所以直接GPT启动。这次选择通义千问，总体下来感觉还是非常好的，国产大模型在代码能力上令人比较满意，在几轮对话下来就写出了想要的程序，还基本没有太大错误，小改一下就能部署到生产环境上。

此外，通义千问还贴心地建议使用cron定时任务，避免长时间运行Python程序消耗资源。这倒也是，也就每隔一个月才跑一次，time.sleep一个月也不是个事。通义千问还建议不要在代码中硬编码账户和密码，建议将这些敏感信息存入环境变量或者加密之后放入配置文件中。总之还是比较贴心的。

下面是小改之后AI生成的代码：
